I think that is a matplotlib characteristic, when one draw a plot

import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0, 10, 500)
dashes = [10, 5, 100, 5]  # 10 points on, 5 off, 100 on, 5 off
fig, ax = plt.subplots()
line1, = ax.plot(x, np.sin(x), '--', linewidth=2,
                 label='Dashes set retroactively')
line1.set_dashes(dashes)
line2, = ax.plot(x, -1 * np.sin(x), dashes=[30, 5, 10, 5],
                 label='Dashes set proactively')
plt.xlim(1, 9)
ax.legend(loc='lower right')
plt.savefig('test1.eps', dpi=1000)

set the xlim will force the X-axis within 1-9, the line segment outside 1-9 hide, but it just hide not be clipped, I don't know how can i actually clip elements with axes extent.

I use Adobe Illustrator to open eps file.
You see it is fine,

But actually it is,

In sometimes, this characteristic is very useful, for example, if one use plt.show() to use the interactive mode, one can drag the canvas to left or to right to see the whole line in the range 0-10.

But in eps file, i do not think this characteristic reasonably, it typically increases the eps file size.
Is it a method to change this behavior ?

Matplotlib: 1.5.X or 2.0.X
